A Virtual Campanile
24th-29th September 2009 – Expo Festival
Leeds Arena, Leeds City Museum, Millennium Square, Leeds LS2 8BH

“Bell-ringing is the most English of sounds. While many nations hang bells in the towers of their churches and religious foundations to call the faithful to prayer, it was in England that the ringing of bells “full circle” with rope and wheel was invented and then elevated to an art form. Only in these islands – and a handful of other places in the English-speaking world where bell-ringing was exported by empire – can you hear practised the art of “change-ringing”, the ringing of bells in fiendishly complex mathematical patterns in which no sequence of changes is repeated.”

Extract from Church Bells by Graham Downing

PEAL_Sketchup+Leeds_Arena_321pxPEAL is an interactive sound installation for The Leeds Arena which models the layout and operation of a traditional church bell tower, replacing the bell ropes by an optical sensing system where lasers act to trigger the ringing process of the individual bells. When a beam is interrupted by a player’s hand, the installation reproduces the ringing of the appropriate bell through a multi-speaker sound system, as if its corresponding rope had been pulled.

This standalone bell tower – or campanile – will reproduce the distinctive ringing sounds and characteristics of five churches spread across the Leeds Metropolitan District and will model the physical characteristics and mechanics of actual rings of bells, to try and provide a faithful experience of some of the skills and techniques required to ring traditional bell changes.

Audio field recordings, HD video and high quality photography will capture the church buildings, their rings of bells and their bell-ringing activities and will be used to create five 10 minute, visually stunning films – one for each church and each of the five screens in The Leeds Arena.

The installation will operate in various modes. As a “timepiece” it will mark the hours and quarters of the day with distinctive ‘named’ changes. In “self-play” mode it will play through (and displays on-screen) a series of permuations or “changes” over periods which might last as long as several hours. As an “interactive” it will show on-screen tutorial materials and a variety of bell ringing patterns which visitors will be encouraged to attempt to reproduce by “playing“ the laser beams. As an “instrument” it will be used for performance by members of Leeds bell-ringing groups themselves.

We believe that the unique sonic quality, physical mechanics, permutational mathematics, historical resonance, community focus and sheer emotive quality of bell-ringing make it an ideal topic for artistic exploration and interpretation – and perfect for a sound art festival that claims “to step out from traditional venues and into spaces that lie at the heart of the community – inspiring practitioners and the public to reconsider their environments.”
